This invention relates to means for cooling 9. generator of an internal combustion motor. the general object of the invention being to provide means for drawing air through the generator by 6 the suction created in the carburetor of the motor, with means for regulating the flow of air and also to prevent back-fire from reaching the generator of the filter means forming part of the invention.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. V r

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, so and inwhich:

Figure 1 is a side view showing an internal combustion motor provided with the invention.

Figure 2 is a vertical sectional view through the major portion of the invention.

Figure 3 isa section on the line 3'-3 of Figure 1.

In carrying out the invention I provide a clamping ring or band I for one end of the generator G, the band being of split construction and held around the generator by the screw 2 passing through the bent ends 3 of the band, this band forming a small air space 4 between itself and that part of the generator which it surrounds. The band is provided with an inlet nipple 5 at the bottom for the admission of air and it is also formed with a split outlet nipple 6 for receiving the end of a flexible tube 1, the tube being held in place by a clamping member 8. The other end of the tube 1 extends into a tubular part or nipple 9 formed on a filter casing Ill. Between the carburetor C and the air filter F of the carburetor a small casing II is located, the casing being provided with the nipples [2 at its ends for receiving the tubular part leading from the filter and to the carburetor. An opening it is formed in the side part of the casing II and a tubular part It surrounds the opening and is suitably fastened to the casin l I and said tubular part I4 is carried by a cover plate I 5 which is detachably connected by the screws I6 to a small casing I1 surrounding an opening IS in the cover part 19 of the filter casing ill, the small casing ll being suitably connected with this cover part l9. An inclined partition 20 is placed in the casing H and slopes downwardly from that side of the casing Ii having a hole It therein to the opposite side and said partition has a hole'2l therein for the passage of the filtered air from the filter F to the carburetor. A down- 5 wardly closing flat valve 22 controls the opening 2| and is hinged as at 23 to the top of the partion 2| adjacent the lower edge thereof and said valve plate has a downwardly inclined strip 24 attached thereto'which passes through the hole 10 2| and isengaged by the inner end of a set screw 25 which passes through a threaded hole in the casing II and is held in adjusted position by a lock nut 26. This screw with the strip 24 acts as a stop for limting downward movement of the valve 22 and, of course, by adjusting the screw downward movement of the valve can be ad- Justed.

A fiat valve 21 is hinged at its lower edge as at :0 28 to the cover member l9 under the opening 18 therein and a depending stop member 29 limits opening movement of the valve 21 to the position shown in Figure 2.

Thus it will be seen that when the motor is in operation the fiow of air from the filter F to the carburetor C due to the suction created by the moving piston of the engine will be checked by the valve 22 so that the suction is created in the casing ll attached thereto so that air will be drawn through the nipple 5 and this will flow around the interior parts of the generator G and then this air will pass into the tube I! then into the casing Ill, through the filtering material It in said casing and then through the opening I8 into the casing H, the valve 2'! being in the open position shown in Figure 2, and then the air will pass through the member I4 and hole It into the lower part of the casing l l and then through the carburetor. As before stated by adjusting the valve 22 the suction created in the parts connecting the casing II to the generator can be controlled or regulated and if a back-fire should occur the force of the back-fire will close the valve 2'! and open the valve 22 so that none of the parts of the invention will be injured by the back-fire.

The member lis placed around the open or brush end of the generator and the invention will not only act to cool the generator but it also tends to remove small particles of metal created by wear of the parts of the generator and other foreign matter will be drawn from the generator but this material is kept from entering the carburetor and therefore the engine by the filtering material 59 placed in the casing it.

It will be seen that the faster the generator revolves, the cooling device will force more cold air through the generator due to the higher speed of the engine so that the generator is kept at a constant temperature regardless of the speed. Also the air passing through the generator is heated and this heated air is introduced in the carburetor which will add to the eficiency of the engine. Thus the device operates to the mutual benefit of both the carburetor and the generator.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall Within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. An internal combustion motor including a generator and a carburetor, an air filter for the carburetor, a casing located between the filter and carburetor, an upwardly opening valve in said casing, means for regulating the downward movement of the valve to regulatethe amount of assasoe I w l air which passes from the filter through the can ing to the carburetor, a second commented with the first-mentioned e leelorv the valve, is filter casings s with the second 6222 .38,

a casingsurrounding a nest oi the gmr and having an air inlet opening and a conduit eon necting the lest-mwtlonerl canng with the filter casing; v

2. an internal combustion motor generator and a carburetor. ;an air filter for th carburetor, a casing located hetween thefilter s and carburetor, an upwardly onelnlng valve in said casing, means for regulat the downward movement of the valve to regulate the amount valve opening it such back-fire occurs.
